There are a considerable number of small mills through New England, the East coast, Midwest, and elsewhere that can fulfil such a request. There are also many excellent remote sawyers with traveling band mills...

Where are you located to get a better idea of to whom to refer you to?

Have you contacted any of the Bandmill Saw manufacturers like Hudson Forestry Products, Woodmizer, etc. They also keep a list of sawyers with their mills in operation...
